Really slow WiFi performance
Sometimes a laptop or other WiFi enabled device on the company or home WLAN shows deplorable perfomance, and it just doesn’t makes sense, because the device works properly, but just on other WiFi networks. The cause of your problem might just be congestion in the WiFi environment in the vicinity of your WLAN.
To troubleshoot the problem you could
- install a network monitor, for example Netstumbler, to discover wireless networks in your vicinity or
- open a command window in elevated mode, and execute this command:
c:>netsh wlan show all
If you discover wireless networks nearby, you should make a note of the channels being used by your WLAN and the other WLANS, if one or more is using the same channel as your WLAN, you may have found the problem. Try changing the channel on your WiFi router to a unused channel and test whether this may be the solution to your slow WiFi performance.
